Does tweaking the Vsb(body effect) make an Nmos pass logic 1? if thats the case, HOW?
 

No. You can decrease or increase, to a point, the "effective
VT" but the "logic 1" (in CMOS logic) is always the PMOS'
job.
 

section 2.4.3.1 in the book " CMOS VLSI Design : 4th edition" by Neil H.E. Weste and David Money Harris says that can be done.
 

Well, then why did you ask?

How about you show us how it works, because to me it
does not. Unless you have some special topology that
attends this alleged ability.
